Sisters of Battle have useful Heavy Bolters, since they can give them Rending.
Honestly, people talks smack about heavy bolters, but they're still a... decent... weapon. A decent amount of dakka, a decent points cost. There are just so many weapons that are better than simply "decent". Autocannons are sort of the case in point, here--roughly same points cost, in most cases, more effective against a broader range of enemies, and still a solid number of shots.
